Mineralogy and magmalogy
I have general interest regarding structures and properties of melts (glasses) and crystals. Melt (glass) structure is very complicated than crystal, so we are trying to study melt structure with various spectroscopic (NMR, Raman, XAFS) and simulation techniques, to reveal its secret. Currently we are especially interested in how water (and other fluids) is incorporated in the melts and crystals under pressure, and what is the role of hydrogen bondings in these structures. In order to get insight of these issues, we are studying nominally anhydrous minerals, hydrous minerals and hydrous glasses usingNMR, diamond anvil cell (DAC) and Raman spectroscopy. We are studying crystal structure of high-pressure minerals using ab initio structural determination techniques for powder X-ray diffraction. Structures of seven new high-pressure phases are solved by this techniques. One of such structures is shown below.
Structure of AlPO4 high-pressure phase (moganite structure)
Simulations of minerals and melts
We have been conducting density functional theory (DFT) calculations to simulate local structures of minerals and glasses. Using these calculations, we have established structure-spectroscopic parameters, especially for NMR spectroscopy. Structure and compressibility of crystals can be readily obtained. We have calculated NMR and EFG parameters of crystals which aim to help interpretation of NMR spectra.
(Also see the facilities page of the our web page)
We have a Micro-Raman spectrometer made of a f=500mm Acton imaging monochormeter, a LN2-cooled CCD, Raman filters, and an Ar-ion laser (488 and 514nm) (also 532 and 782 nm lasers available). Various object lenses including Mitsutoyo's long-working distance are available. The laser beam can focus to ferw micron. This Raman spectrometer can be used to study naural samples, high-pressure samples synthesized at high-pressure labs, and to determine the pressure of diamond anivl cell (DAC) using ruby fluorescence. Since it uses class 3B laser, the user first get training before use. English manual is available. Very recently, I introduced Ondax's SureBlock filters which enable us to measure down to 5 cm-1, so terahertz region can be measured with our spectrometer.
Our home-made Micro-Raman spectrometer
We are trying to establish the diamond anvil cell (DAC) laboratory. So far, three DACs (Merrill-Bassett-type, piston-cylinder type and plate DAC) are available. We have CO2 laser (100W) for heating. As noted before, the pressure of the DAC can be measured using a ruby chip and Micro-Raman spectroscopy. Diamond and moissanite (SiC) anvils are available. Very recently our institute has installed micro-focus X-ray diffractometer. Now I'm planning to do in-situ X-ray diffraction experiment using this new X-ray machine.

We are always looking for prospective graduate students and post-doctral fellows. Please contact me for current information. Currently we are accepting application for international intern student program (2016 application: closed)
